+VC API exchanges are expected to be short-lived but they can be combined with other mechanisms to enable longer interactions.
+Examples of other mechanisms include SMS, email, web notifications, or phone calls.
+This approach simplifies digital wallet implementation and allows
+existing mechanisms to be reused without reinvention within
+the VC API. The Web or native platforms are expected to enable
+additional interactions via applications (such as Web browsers)
+or other platform features.
+For example, in asynchronous issuance, a holder requests a credential but must wait for processing.
+In such cases, VC API components (such as an issuer coordinator) make
+use of mechanisms outside the VC API to notify the holder when their
+credential is ready for collection.

 The following APIs are defined for using workflows and exchanges for credential use cases that require crossing trust boundaries:
